- To all whom it may concern.-

Be it known that I, EDWARD AUs'rIN WAT- SON,-. a citizen of the United States of America, and resident of Greenville, in the This invention relates to spinnin appa .ratus and particularly to a device or con trolling spinning machines to cause them to operate for producing a preliminary winding near one end of a bobbin or receiver and thereafter a main winding on said receiver. An ob ect of this invention is to produce novel means for causing the ring rail to move in a short traverse while the preliminary winding or short stroke is being installed on the receiver or bobbin and for automatically changing the traverse of the ring rail to apply the main or service winding.

A further object of this invention is to provide novel means associated with and auxiliary to builder motions now in common use, thereby making it possible by such association to produce the desirable results without changing standard constructions and by mechanism which can be attached to builder motions now in common use without materially increasing the cost.

A further object of the invention is to produce novel means for utilizing mechanical parts of a builder motion for actuating the control of the preliminary winding and for restoring theelements of the builder motion to normal position to direct and produce the main winding operation.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification wherein like characters denote corresponding parts in the several views and in which- Figure 1 illustrates a sectional viewof a fragment of a spinning machine showing a device embodying the invention in elevation;

Fig. 2 illustrates a View at right angles to that shown in Fig. 1;

Figs. 7 8 and 9 illustrate perspective views of details of the device;

. Fig. 10 illustrates a view in elevation of a wheel for operating the device; and

Figs. 11 and 12 illustrate modified-constructions of mountings for the attachment.

In these drawings 15 denotes a frame of a spinning machine, 16 the ring rail, 17 the lifting. rod, 18 a shaft, 19 a jointed arm for operating the lifting rod, 20 a segment for partially rotating the shaft 18, 21 a chain connected to the segment and to the builder arm 22 which parts are of ordinary construction and well known and need not be described in detail. It is believed unnecessary to further describe the operating parts associated with the builder arm except those which constitute improvements forming the subject of this invention.

In carrying the invention into practice, I employ the-usual builder cam 23 and attach to it or mount on a shaft with it, a short. stroke cam 24 which is of considerablyless diameter than the builder cam.

The builder arm in the present embodiment of the invention is supplied with a post 25 in which a shank 26 is slidable, one

lan view of one end with the device in opend of the said shank having an arm 27 anchored to it so that the arm 27 is movable laterally of the builder arm. The shank also has a pin or stud 28 connected to it, which stud enters a slot 29 in the head 30 of the shaft 31, which shaft is rotatable in brackets 32 and 33 carried by the builder arm. The shaft has a wheel 34 applied to the threaded end 35 of the shaft 31 and the wheel is held on the said shaft by a nut 36 so that the wheel may be operated to rotate the shaft. The periphery of the wheel 34 has a notch 37 for a purpose to be-presently explained.

The brackets 32 and 33 also constitute guides with relation to which a bar 38 is slidable and the said bar carries a plate 39 having ratchet teeth 40 on its upper surface 27, it being shown that the outer end of the said arm has a sleeve 42 attached to it in which a reciprocating rod 43 may move, the said reciprocating rod having the ratchet 41 pivotally connected to it as at 44,!whereas the opposite end of the said rod ha a head 45 in which an anti-friotion roller 46 is rotatably mounted. A spring 47 is interposed between the sleeve 42 and the said head 45 and is operative to urge the head away from the sleeve.

One end of the bar 38' is bent back on itself to form a hook 48, the said overlying portion of the bar being adapted to enter the notch 37 in the wheel 34 to hold the shaft 31 in position where the arm 27, will support the ratchet 41 in operative relation to the ratchet teeth 40 The wheel 34 has a stud 49 to which a spring 50 is connected, the opposite end of the said spring being anchored to the builder arm" so as to exert a pull for partially rotating the wheel 34 when it is relea ed by the overlying portion 48 of the rod 38.

The builder cam, under ordinary operation, rotates on the roller 50 by which the builder arm is oscillated, but in orderto move the builder arm in relatively short sweeps, the shank 26 has an anti-friction roller 51 rotatable on its end which is adapted to be moved into engagement with the short stroke cam 24 at the same time the ratchet 41 is moved to aline and operate in conjunction with the ratchet teeth, and the said roller 51 and arm 27 are moved together with the shank 26 under the influence of the shaft 31. The anti-friction roller 46 and the roller 51 are both engaged by the short stroke cam when the shaft 26 is moved longitudinally of its axis and when the parts are in the position shown in Fig. 4, and when in such position the short stroke cam will successively move the ratchet 41 in engagement with the ratchet teeth and force the bar 38 longitudinally of its axis until the portion 48 of the bar disengages the wheel 34, thus permitting the spring 50 to partially rotate the said wheel and consequently the shaft 31 which will cause the shank to oscillate in its bearing and carry the parts to the position shown in Fig. 5 of the drawing when the roller 51 and anti-friction wheel 46 will be disenthe full motion which is ordinarily im-- parted to it by the builder cam.

From an inspection of-the drawing, it will -might in some instances be be apparent that this device can be attached to builder arms now in common use and that it constitutes a simple attachment for reducing the traverse and that it is comparatively inexpensive owing to the fact that the ordinary builder cam can be sup-- anil the other of which projects from the shank E. The shank D will have a roller .on it similar to the roller 51 whereas the shank E will carry a bracket L in which the ratchet operating mechanism is mounted as will clearly appear, The shaft G in this form will be operated by' and under the control of mechanism similar to that heretofore described and need not be further referred to.' This modification is provided as showing another method of carrying the ratchet and its operating mechanism and it preferred to the other form.

I claim- 1. In a traverse controlling mechanism for spinning machines, the combination with a builder cam and a builder arm, a traverse controlling cam auxiliary to the builder cam andcarried thereby, a rotating member mounted on the builder arm adapted to engage the second mentioned cam, an escapement controlled by the, second mentioned cam, means for holding the roller and escapement inoperative relation to the second mentioned cam, means whereby the escapement causes the release of the said means, and means for moving the said roller and escapement out of operative relation to the said second mentioned cam.

2. In combination with a builder cam, a

traverse controlling cam carried thereby, a
